Hey guys last night I had two ballsdrilled. When I got home I noticed one wasn't drilled right. I asked for a stacked drill pin over the ring and it got drilled pin over ring with cg in the palm. A label leverage you might say. I am furious but what if anything can I do? I know he'd fix it for free but I am not gonna have a brand new ball that's never been thrown plugged.

I try. It is hard to tell on your previous post if your being sarcastic or not.

The bowler info can be entered manually or used the info they allow you to choose based on bowlers skill level. For all charts I used the bowlers specs given for a 220 average bowler.

Is there a specific thing you would like charted with the software to compare cg placement based on a bowlers style and the said results?

Additional info on ball studies can be found here

The picture shows the bowling info used on all charts posted along with what info is needed if trying to chart for a specific bowler or style.

Lucky, also realize both balls in that study that produced 2-inches of recovery difference were illegal in the positive and negative weights.  Two bowling balls drilled "leally" would in theory produce less of a difference.

No one is saying it has zero effect.  They are saying the effects are not enough to base a balls success solely on whether or not the CG is in the palm or 1-inch to the right.  There are other factors which give the bowler more room to adjust reaction for what they are trying to achieve. 

I would be more worried if my abralon pad was used 2 times versus 4 times then where my CG is located.  But that is me.

Kidlost2000,

I would like to thank you for your effort, time, and patience with me.

I note about an inch in difference in pocket position, a degree difference in attack angle.

In this link posted above I note 2 inches difference in pocket position right from the USBC's own test.  Or as the researcher stated about a 10% difference in ball reaction.

When we own the pocket and are trying to carry, by moving left or right, up, tucking our pinkie finger etc.  How many of us wish for an extra 1/2 inch in the pocket or inch to kick that corner pin out!

According to the USBC test above it looks like CG adds up to almost 10% in their tests!  What competitive bowler is willing to give up 1% to his competitors!?

I guess then "CG Maddeh" that is why we have no tournament winners posting in my other post "Around the corner tournament winners".  This post is looking on Ballreviews (a worldwide site) out here that have won tournaments playing inside with the cg's in a negative position while playing deeper than the 4th arrow.  Not yet!

Do I think it is conceivable that someone could show up and post there?  Yes, but I maintain that it is only because the guy is 10% better than his competitors and or the lanes were scorched in the mids so bad the friction of the lane supplied the midlane, not the ball core!

REgards,

It's conclusive!  Thanks guys!  CG DO MADDEH!
PS notice the poor rev dominant axis rotation strong bowler above, almost 28 boards of hook versus 14 boards of hook for the 30 degree axis rotation top pro player with less axis rotation and more speed!  Easier to control I'd bet.  But for the soft high axis rotation player I bet you it is exciting when it works!

I can wheel a ball with a negative cg placement deeper than 4th arrow!

That's cause you're a beast, bro.

That's cause you're a beast, bro.

actually, its because I've mastered the art of suitcasing the ball
